Question

an f factor has a mutation that affects the ability of relaxase to join single - stranded dna. it does not affect the other functions of relaxase. at what stage of conjugation would a cell containing only f factors with this mutation be stuck? multiple choice the f factor would not be cut at the origin of transfer the f factor would not be able to be transferred to the exporter the f factor will be stuck in the conjugation bridge the f factor will move to the recipient cell but will not be circularized

Explanation:

Relaxase is involved in nicking the F - factor at the origin of transfer and also in circularizing the single - stranded DNA in the recipient cell. Since the mutation affects the ability of relaxase to join single - stranded DNA but not other functions, the F - factor will move to the recipient cell but won't be circularized as circularization requires the activity of relaxase to join the ends of the single - stranded DNA.

Answer:

The F factor will move to the recipient cell but will not be circularized
